"It's a futile attempt, and as I tell my kids, these are the rules," Huckabee Sanders told Fox News' "America's Newsroom" program. "If you don't like the outcome at the end, you don't get to change the rules."

She said she believes the Trump team has done all it needs to do to secure the GOP nomination, including with Trump winning 38 states.

"He won more states than any other Republican presidential nominee ever has," she continued. "This is an election process, not a selection process. This isn't something the party elites get to come in and change. If they try to do that they will be overthrown by the bulk of the people in the convention."

Further, she said she believes the Republican National Committee will take the steps necessary to make the convention a great one.

"We have an incredible lineup set up, and I think we'll come out of this strong and better prepared and united to defeat Hillary Clinton in November," said Huckabee Sanders.

She also defended Trump over the controversy surrounding a tweet that was posted on his account that depicted Clinton atop a pile of money and with a six-pointed star, which was later changed to a circle.

Trump Wednesday night added to the chatter by posting a photo of a Disney book with a similar star on it:

"I think they are trying to show the ridiculousness for the attack," she said. "It's a distraction by the liberal media and Democrats to take away from the Hillary Clinton scandal. The real question is they are trying to push that Donald Trump dislikes Jews. Absolutely not. His son-in-law is Jewish. His daughter is Jewish.

"Those are two of the most important people in his life. To make this anything other than what it was, just a basic tweet is absolutely ridiculous and he should push back when people try to portray him as something he's not, particularly when it's so personal and close to him."
